Yep, SMTP and the whole spam fighting part of the Internet, isn't ready for IPv6. This is not IPv6 fault. I have repeatedly tried to get people interested in methods of making it possible for ISPs to publish their "per-customer" allocation size, so far without any success. Most of the time I seem to get "we did it a certain way for IPv4, it works, we don't want to change it" from people. IPv6 changes things. Lots of things. There will be a lot of work to catch up. It's too bad that the part of the ecosystem that fights spam have woken up so late. -- Mikael Abrahamsson email: swmike@swm.pp.se
